imageboards

Hey ^EXPERT _PROGRAMMERS
I want to make something that'll archive the imageboards I want. I know the text field is limited to 2000 characters, but what about the name/mail/subject ones? Oh, and how does it work with unicode characters?

That's great then.

Can somebody explain now how can I use regexes? I know I can use them to find all substrings where the RE matches, but is that all?
