Hello,
My name is Augustin and I use kdenlive on Kubuntu :)
I am also a Drupal developer, so I know Drupal very well. I developed many modules for Drupal.
I would like to post a follow up to the following thread:
http://www.kdenlive.org/forum/website-development-mantis
I definitely think that for the good of the kdenlive project, the whole web site should be fully integrated. Users are more likely to contribute something if they don't have to use different logins for each part of the site. So this site should definitely use the Drupal bug tracker to replace Mantis. It might be a bit of work to do so at the beginning, but the long term benefits are worth it. We don't need to import all mantis bugs into the new bug tracker. The Mantis bug tracker can be cleaned little by little, as bugs are actually fixed and duplicates created in the new Drupal bug tracker.
Also, this web site should definitely have a wiki (a simple node type called 'wiki' should be enough to start with), to encourage users to improve on each other's tutorials. The tutorials themselves and the user manual should be like a wiki, editable by every (trusted) member.
Finally, I am not particularly fond of forums. Too much information is lost in active forums... but that's something I'd like to discuss later, after the rest of the web site is properly integrated.
Blessings,
Augustin.

Bonjour Jean-Michel,
It's good to know that you've planned to use the integrated bug tracker.
I am hosting my Drupal sites at dreamhost , where the memory limit is 90M by default but can be overridden with .htaccess. In any case, the memory is sufficient for my Drupal sites (inc. the project_issue.module).
You are using Drupal 6, right? There is no official release for the project*.modules. Have you checked that nothing in the following list of issues could be a problem for you?
http://drupal.org/project/issues/search?projects=Project%2C+Project+issu...
Because of the lack of official, stable release for D6, my own sites are still using Drupal 5.
Btw, I wanted to write to you over a year ago, to advise you to use Drupal to integrate forum and bug tracker. I'm glad that you found your way here yourselves :)
