I'm almost finished with a new File Manager module based on the free open source SeekDotNet File Manager Its pretty sweet and was easy to integrate.
I'm also using a free and open source HttpModule for file uploads written by Chris Hynes. Its called SlickUpload and it can handle very large files and supports a progress bar easily. It also integrated easily with just a few lines of code and a little javascript. I've been looking for something like this for a long time and am really glad to have found it. I've used the ABCUpload control and its pretty nice too but I needed a free one for this project since this project is free and open source.
For those of you who had troubles with the last release I promise to test the installation process more carefully, there was some bad data in the initial data creation scripts. I don't have an upgrade procedure in place yet but thats one of the reasons I'm still calling the releases alpha. I think you can upgrade though by replacing all the files and then carefully comparing the table and data scripts to your database and modify your db where needed. At some point I will have an automatic upgrade process but thats my best advice for now. I'm shooting for a new release by Sunday evening hopefully with both the new Image Gallery and File Manager modules.
I'm also happy to report that the performance improvements in mono for ASP.NET are very evident since they upgraded the servers at monoForge to the newer mono 1.1 branch.
Exciting times at mojoPortal!
