Time-outs are only avoidable by either copying what you wrote and paste it into a Word document, or to write everything in a text editor program, then copy and paste it into the forums. For your iPad3, there are a few programs you can choose from that would allow you to do this: Doc2, Pages, Office 2 HD, Documents to Go, Quickoffice Connect and probably some others. Once you're done writing, select the text, copy it, open PC and paste. Alternatively, you can save it to your iCloud (I believe Pages does this right away, not sure about the others) and then paste it.

I haven't used iCloud before but if it doesn't let you do this since it's purely text, take a screenshot or convert it to .pdf then try. For this, you'd take a screenshot also then paste them into the forums. It's a longer process that hopefully you won't have to do.

Even if you're on a iPad3, you can still be logged out due to a time-out.
