All-round great addon, with helpful, prompt support whenever we've had to get in touch with Xon to resolve any issues we find. Would definitely recommend this to anyone who makes use of the conversations system, regardless of how small or large their forum is.
One of essentials addon if you just think about private conversations on your forum. Great addon, many great possibilities to arrange settings per usergroups. Support is excellent, developer Xon is open to suggestions. All in all, if you need very good addon and great support, take this one, you will not regret.
