If you need help while using RapidSMS, there are several ways you can get it.
Ask on the #rapidsms IRC channel on Freenode. You can use the webchat client for this too. The #rapidsms IRC channel, like most IRC channels, is pretty informal. You don’t need to ask whether it’s okay to ask a question - just ask it.
Ask on the rapidsms mailing list. This list is used to ask and answer questions, help work through bugs, and discuss general RapidSMS topics.
Note that there’s a second mailing list,
rapidsms-dev. You’re welcome to join both, but
rapidsms-devis intended for discussing development of RapidSMS itself (changing the RapidSMS code), while
rapidsmsis to talk about using RapidSMS, writing apps that use RapidSMS, etc.
