Not to be rude, but if your pool isn't merge-mining, then your pool is stupid.
The pool isn't merge-mining

It just runs 'standard' XDN Team's pool software

I saw, but now that you can merge mine XDN with another parent coin it makes absolutely no sense to mine without merge mining. No sane person should mine at your pool. It's too bad minergate is only merge mining pool, and that there's no open source merge mining pool software, but that is the situation at present.
