Hi John, many thanks for responding.
If you could add the functionality of being able to auto add categories in the same way as tags that would be fantastic, would that be a simple task?
I have tried to look at the source code of the plugin to see what would be needed but I am out of my depth!
I am using the plugin for a rescue animal rehoming website where we aggregate posts from another source (our forum) and am going to request the posters add codes such as #beagle #age3 #male in to their posts that will correspond to the auto tag/category, then people can do a more in-depth search on the WordPress site.
I would like to use categories for info such as the breed so that I can separate that from age, gender etc.
Custom taxonomies would be interesting from a WordPress fan point of view, but is not necessary for my current project if it's a lot of work to implement.
I'm happy to send a small donation ($10 or something?) towards development if your time is limited as this plugin would really help me out, although I am working pro-bono for a non-profit organisation so if you are happy to provide it for free that would be great too.
Thanks again for your time :) Much appreciated.
