[Slackbuilds-users] Script submission technicality

[fsLeg]

I just realized something. Anyone can submit a SlackBuild. There's no 
authorization, no checks who actually submits it, and even Submission 
Guidelines don't mention anything about who can submit SlackBuilds. Even 
existing ones. So while it would be a good courtesy to notify some 
script's author that a new version came out or there's a bug in their 
script, you could just fix it yourself and submit it without changing 
author and maintainer fields. If it's a good-willed change, you just 
specify your own email when submitting a tarball. If you're slightly 
less good-willed, but still want the SlackBuild to just work, you can 
specify the maintainer's email, and it doesn't even matter since it 
seems that nothing is actually emailed when you submit a script.

So does it mean that it's actually OK to submit updates, fixes and 
changes to existing SlackBuilds yourself if their maintainers don't do 
it in reasonable time? At what point would that be considered a 
takeover? Or is this just an oversight in the guidelines?

And side question, since I mentioned a takeover.  I emailed maintainers 
of two SlackBuilds and asked them to update their scripts, but got no 
response in two weeks by now. How long should I wait before asking here 
to take over their SlackBuilds?
