more functions on this forum are pretty ok, even Chinese forums offer more images, functions etc
Not sure what you mean by "more images"?
This forum is run on phpbb, which they claim is the largest forum platform in use ... not sure how they come to this conclusion. But limitations are at the source, generally.
TeaChat is an odd forum, it is not really
run by its owner, Adagio. They do some basic stuff to keep the forum running (for which we are very grateful), beyond this they are pretty much, "hands off" as they go about their business of selling tea over the internet
There are many more pros than cons to this approach for the types of members TeaChat attracts most. But the one con is that they are not going to pour tons of money into the forum to make it ideal to our standards, not even to my standards ... especially when we are not going to spend all our TeaBucks at Adagio. They cater to a sector of the tea market very effectively, but most of us are not in that sector.
However, I have asked ownership for certain improvements to make TeaChat more functional with more features.
Steepster comes to my mind ... they have added a lot of features, and to do this, it needs to be funded. Thus they "sell" and "market" (see my email inbox) and you sometimes get the feeling that Steepster is generally not as objective. Members are sometimes privately contacted and asked not to post certain things. especially against a contributing vendor.
TeaChat does have its OTTI, NOTTI and SO programs ... but these seem to have much different objectives in mind.
Still, I admire the work they have done there ... but I have not been personally motivated to jump in.
