Help Technic/Solder help.

[Pyrii]

I'm creating a modpack for my server to help keep my friends and other users up-to-date on the mods required to play. It used to run from 2012-2013 so I'm reviving it, hoping to use Technic to make access and updates easier.
 
I have noticed though that I can't make "DerpyCraft" on the platform (It's made and I'm working on it in Solder at the moment). There seems to exist a pack with the same name that's never been updated or used in any way. So I wondered if I could reclaim it for my own ACTUAL use? The rules do state that "Inactive packs will be removed without notification."
 
 
As for solder, I'm running 0.6-DEV and I keep getting this error at random intervals:

Unhandled Exception

Message:
Directive 'magic_quotes_gpc' is deprecated in PHP 5.3 and greater

Location:
Unknown on line 0

considering the requirements listed a minimum version of 5.3.xx, I think removing depreciated commands would be helpful.

Apache version 	2.2.23
PHP version 	5.3.21
MySQL version 	5.5.35-cll

Thanks in advance.

Sorry for the bump, but I have an extra question regarding solder. Is it possible to know the IP of the platform server that accesses the API on my server? I'd like to restrict access to my home IP and the technic platform server for security reasons.
