Question How to synchronize users - automatically

Tried some more. I have a usergroup "members" that have additional forum access.

Events look kinda like this now:
1) Register new user -> gets access to forum.
2) Pays membership (PayPal) -> gets upgraded to Joomla usergroup "members"
3) Syncronize users in admin panel -> user gets access to member area of the forums
4) Degrade to usergroup "registered" -> user still has access to member area on the forums
5) Syncronize users in admin panel -> user has no longer access to member area on the forums

So basically, 1 & 2 I am happy with, this works as expected. From then on out there is some fixing to do.

How can I automatically syncronize the users? If I cron the admin link then won't it check if it's running trough Joomla? Running scripts from outside shouldn't work, after what I know anyway.

Unfortunately that is all the advise we can give you regarding synchronizing users JimL. The sync function in Kunena works as intended, beyond that there is not much else we can do.

You should try getting in touch with your host and ask them to follow you through to set up the cron job to execute the cron job for that. I use hostgator and I had them help me set up a cron job about 3 months ago and they followed me through every step.

Ok then I must clearly be mistaking something, somewhere. Is it really intended to not change user group access until you manually syncronize?

Setting up a cron job is no problem at all. I just can't understand how I can execute "syncusers", admin.kunena.php which handles it terminates if it isn't called trough Joomla...
