I like their business model of 'pay for support' and get additional functions'
The component has some nice features, such as split columns, which I've not seen in other components I've tested.
Will be standardising on this in the future.
I've just completed a site for a trade association that wanted to have a directory of its members. Mosets tree gave me the flexibility to tweak it to their exact requirements, almost completely without having to hack code.
Furthermore, the support I had was excellent. I had the nightmare of exporting data from a legacy Access database, but the built in importing facility made life quite easy. When I did hit problems the Moset support team got answers to me usually within 24 hours.
(I also have another site that's been running with Mosets Hot Property for a few years without problems).
Cannot recommend this highly enough.
1. Ability to allow a user access to one forum but deny access to another
2. Ability to create custom profile fields that were displayed when visitors look at a user's profile
Although the author goes to great lengths to state that the component is beta I have experienced no issues in the front end, and only one in the back end, which was not a showstopper anyway. The support forums for this component seem to be very active as well, which is always a good sign.
Two thumbs up!
