Daily posting restrictions enforced in support requests

[Makoto]

Steps to reproduce:

1. Set a daily posting limit for any member group
   
2. Exceed this posting limit by any means
3. Create a support ticket
4. Attempt to reply to said support ticket
   

You will be able to create support requests even if you've exceeded the daily post limit, but you can not reply to support requests.

Thanks, I've logged an internal bug report for that issue.
