[server-admins] Forum upgrade

[Manfred Bergmann]

Postponing the upgrade to early next week.
The procedure is unclear to whether database upgrades are necessary for 
version 1.3 of the forum.
Awaiting some answers from the developers first.

Currently we have a strange issue in the forum. The captcha image is not 
visible. So right now no one will be able to register.
Found this in the logs:

Looks like the captcha image is attempted to be stored to a temp folder 
but this fails.
Not sure though where mvnforum is trying to store the image.
