Loved your blog post: "How To Accept Donations With WordPress? – WordPress Donation Plugins"
The last plugin (8. Total Donations) however is no longer being updated or supported. This is a great pity... it had great features.
Thanks for the quality of your blogposts.
It was updated around 8 months ago which is still not too late.
Regarding support, Their team had recently moved the support from ThemeForest to their own website.You need to verify the purchase code to avail Free support.
I hope it helps.
