>>>Tracy, I disagree here. Putting someone on your twit filter list means that you don't like to interact with that person. In a COMMUNITY that implies that you will have to refrain from ANY conversation that the twitted person is part of. So, the code should be:
>>>
>>>

IF ANY participant of this thread is on the reader's twit list
>>>   thisform.ButtonReply.enabled = .f.
>>>ENDIF

>>
>>Regardless of how you would like it to work, I think you'll find that the UT twit filter operates in exactly the same way as every other twit filter I've ever come across. There is nothing exotic about it. You are using a water pistol to put out a forest fire if you want the standard twit filter operation to change.

>I think his proposition was kind of a joke. Anyway, do you know some other forums that have implemented the "twit filter" functionality? I never came across one.

I find that exceedingly surprising. Are you sure you weren't simply unaware of it?
