As many of you know, I've been recently launching MathOnline, a site dedicated to collecting (in a somewhat organized way) mathematical material. I'm now taking advantage of the offer of Scott to post one more question about it.

The problem is how to promote it effectively. In these days I got some subscription, but there are sadly few books added and even less votes and reviews. I guess that's part of life, maybe people just don't want to hang around a site of commented lecture notes. But I'm wondering if someone can be done. So I'm asking your advice (and maybe your help): is there something I can do to spread the word better about MathOnline? What I've done so far is posting this here and advertising it to some friend in universitied all over the world, with the request to tell where they work.

I think one of the main points would be to reach undergraduates (and graduate students in their first years). These are the people following more courses, and they have a lot of free time to help there. Unfortunately, I'm now in a research institute, hence I have no teaching duties this year.

Another thing I may do is keeping adding material until I reach a critical size. Indeed I usually add one thing or two every day, but I think I'd rather spend my time developing the missing features and... well, doing mathematics :-). Any other ideas?

@Harry: You realize also that a lot of people are not doing finals, or teaching, or anything related to classes this week, right? :-)

@Kevin: Everyone in #math-ag has been silent for the past week, and they're all over the country, which was what motivated my statement.

@Harry: No, I'm not american, so I did not realize this. Different countries have different deadlines :-)

@grp: Indeed I think it was of big help that MathOnline was mentioned on the SBS. I don't know personally much bloggers, maybe I should write them anyway.

@Scott: Thank you again for your help!

To quicken up things I have directly turned you into a confirmed user. Also, if you wish, I can promote you to moderator. Not that there is much activity to moderate now... :-) (of course I can promote any other high reputation user)

Actually there is :hover magic, as the arrow should turn into a hand (or whatever your set of icons defines as a pointer).

For the spam, I don't know. I can think of three reasons.
1) I may be missing some headers (but which ones?)
2) Maybe other people on my server, which is on shared hosting, are on blacklists, so that IP is considered harmful
3) Gmail sends some particular headers and SPAM filters recognize that the mail actually does not come from the Gmail account it claims to be (of course it cannot, since it is sent by my server).

I frankly don't know what to do (maybe changing address would solve 3). In any case, people using openid login do not need to confirm anything, so maybe I could just make the openid login more prominent.

They separate graduate students into masters and doctoral students? That's somewhat surprising.

Harry- Actually, it's not surprising anywhere; it's just a lot of US universities don't, in practice, take any masters students. There is then the further caveat that how these notions correspond to things in other countries can be a bit complicated. I don't know where Dror is, but for many years, Germany, for example, didn't have a Bachelor's degree; going to university meant getting a Masters.

@jonas: I suspect that if you reread the title of this discussion, you will see what is wrong with your post. =p

@Kevin: thank you for your suggestion. I have just posted there.
