I know a lot of users would like more customization to the product. And our community is willing to "pay" however I am sure other communites would be willing to pay.
How about having a module that controls the default user avatar so instead of this 123 Flash Chat tweety bird user avatar icon as the default avatar, give site owners a bit more freedom with a module to un leash the power to make their chat that they spend money on to make the site feel their own. I would say anywhere from $99 - $249 for this module. If $249 maybe you can help make the small icons for the client to go with the module
Just an idea but again we have lots of ideas this idea is focused towards a module, so your team can keep the fresh ideas but also give users a bit more freedom and customization to "their" site.
This idea will also bring in new income for your company
