I'm really interested in aMember and would be looking to integrate this with my current CMS, Modx. I noticed on your Integration Plugins page and your Order page that there is no mention of a Modx plugin yet. BUT when I had a look at the backend admin via your online Demo there actually was a Modx option in your plugins list. Has this Modx plugin been developed already and be available at the standard $40 like the other optional plugins? Or will this plugin need to be developed from scratch at a quoted price before being available?
