How to create a '--max 5 patcher--' in Max 7.06 so I can share patches here?

Hi there, I'm unable to make a '--Max 5 Patch--' so that I can share patches on the forums. I have tried 'open as text' and saving it but the forum site doesn't allow .rtf files. I've also copied, pasted and saved the text as .txt but that didn't seem to work either. I'm sure there must be other people who have this same problem and I would really appreciate some advice, links, please? Thanks in advance :)
