I grabbed JForum a few days ago when I was looking to add a java Forum feature to one of my sites. I've coded some enhancement for a few things I wanted, and thought it might be a good idea (belatedly) to post details here to ensure I'm not duplicating someone elses work. Also, the changes I've made so far I did not pull from CVS but made to the sources that came with 2.1.4 download.
1) Avatars being located within the webapp bug me, so I've added some properties to SystemGlobals and changed the necessary files to be able to store and pull avatars from outside the webapp
2) I've redone all the graphics to remove the white background anti-aliasing, and modified the CSS to remove the supporing background images.
3) This is just config related, but I've moved the HSQLDB to outside the webapp
4) Added attachment image detection and thumb creation so that posts with image attachments can directly display the thumb as a link to the image.
Most of these changes allow me to develop in Eclipse and build a war file that I can drop in the server without fear of wiping anything out. [originally posted on jforum.net by TwinFeats]
