We have free add-ons
, and we have paid add-ons
. Paid add-ons come for a fee, mostly, each of them costs $7,99. Each add-on has instructions (README.txt) inside of how to install it. Instructions are in English.
If you doubt how to install this or that add-on, you may use an auto-compiling tool
to get the plugged-in version of miniBB in seconds, and then install it on your end. Paid add-ons are also available in Compiler. For plugging them in automatically, you should be logged in as a Customer, then going to Compiler - Paid add-ons you have purchased, will be available to compile amongst free options.
Let us know if you get the idea what to do next :)
