Question About the Forums for the Moderators

How/when are posts auto-deleted? It seems that some sections of the forums delete posts when those posts are older than X months. Is this a universal implementation or is it different for each subsection? Does Utilities and Resources have such an implementation?

I’m looking into implementing a ‘check for updates’ system into GDSearch that will parse that thread for the

<!-- message -->
		<div id="post_message_391435">
			<b>VERSION: 0.5</b><br />

HTML code, extracting the version and comparing it to the one in the application, and then notifying the user if they could get a new version.

Is this ‘safe’ (until the forums go down) or should I look into some alternative?

Thanks!
