Hi!
Recently I installed owncloud 4.5 on my server and it is very very nice. (take a look at
https://owncloud.thomas-steinbrenner.net/ (test//test))
Now I am using OC to share files and collaborate with a team of people (I think OC has a lot of potential for collaboration) but I also love DokuWiki.
OC has a plugin system, they call it Apps (the stuff on the left side of the screen). I would love to see a DokuWiki-App for that, but I am afraid this might be above my skills. So I hoped I could get you people excited about OC :]
Cheers,
Thomas
