I'm happy with things now.
Sure, we don't have much in the way of styles, but we have one that mostly works. That's enough to get the ball rolling. There's plenty to use & test.
Based on the recommendation of thewalkingman, I've given the following users 50 MB of disk space:
You can access your stuff at http://pics.livejournal.com/username and when you use the client, upload to firstname.lastname@example.org
I'm officially taking bug reports, usability complaints, and feature requests.
And if you want to join the beta-testing squad, email me your LJ username and a brief description of your computer skills, interest in the project, and familiarity with similar tools. Please, only committed testers... I crave lots of quality bug reports and suggestions.
I only have so much disk space to give out for now (it's all running on my personal server), so I'll only be giving out disk space to people that meet criteria not already met by a number of other people. That is, I want many different types of users. More than 1 of each is good, but not 50 of each.
I intend to reply to everybody, but if I get flooded, I may not reply. In that case, just wait for the next beta testing round. Each one will get larger in scope.
