Support for linickx plugins has always been community driven, but recently I've had a few bugs and patches submitted via email.
To make like simpler I've found that I can track bugs using trac - bad pun!
Here are some links :)
- PHPBB Recent Topics
- Root Cookie
The difference between the two is simple: if you want help then click the support link if you want TO help then file a bug or submit a patch :)
