Hmm... I hope Yiannis can submit that soon. Anyway I think you should talk to your isp, i've heard some ports are blocked by default by certain isps, but they can be opened by user request.
My ISP is a free one, provided by my collegue; its crap and access is blocked on many pages, as well as ftps (and cvs seems like too...). Theres no way to "talk" to them since its free as I said (but I cant afford a good ISP), and its provided with "educational purposes", so Im stuck :cry:
We plan on providing nightly source snapshots, so stay tuned
Ok, hope very soon as I really want to have the "bleeding edge" and see whats new.
[edit]
Mmm, I just realized you can access the cvs via web
http://cvs.sourceforge.net/viewcvs.py/codeblocks/But... downloading the files one by one... Ill wait for the snapshot!
