Going to clamwin, it is absolutely not obvious where to submit bug reports / feature requests.
First try: "How you can help" link. This suggests that feature requests and bug reports are welcome, but doesn't link to the tracker.
2nd try: "Contact us". Web form only, not clear where the generated email goes, it's certainly not the right place for bug reports.
3rd try: the "Project on SF.net" link. Ok, in theory I'm in the right place, but sf.net 's web layout is a mess. Not your fault, but it doesn't help.
Finally I find that I need to click "Support" (which is stupid for me, I don't need support, I just want to submit a feature request.)
Also: like so often, I need to have an account to submit a feature request. Personally, I don't like that but I know it's state of the art. (Note that we don't have much of a problem in the Debian bug tracker, where you don't need an account.)
That said: thanks for providing this software!
