In an attempt to fix the spam issue that has been plaguing the forums for some time, changes were made to the registration process. With these new changes came some new issues. One of those being that new users cannot post new topics to the Alfresco Forum.
If you are looking to post and contribute to the Alfresco forum you can do two things. One, post here in this thread (Which I think any user should be able to do) and I will grant your account user rights. Or two, send an email to Community@alfresco.com with the account that needs posting privileges. Either way I will be able to see that you need to have adjustments made to your account and I will act on that promptly.
Sorry for any inconvenience that this causes anyone.
