I here am casual, but was specially registered to participate in discussion.
Hello Antoniomup! If you would prefer to be called something else, please let me know. Welcome! Casual visitors are welcome too! Of course we prefer participation, but that is not required. The ACTS forums used to be quite popular and busy when on (now defunct) YahooGroups, and it took me a while to select another forum (I tried a couple of others too). We've landed here!
Feel free to ask questions or discuss just about anything you want - there's a forum for it here (or can be!).
