First, love this site. I am busy putting in all the cards I collected over the past decade and this is by far the best application I have found for that purpose.
That being said, are there any plans for other card games? Personally, I would love to see the Pokemon TCG added in. I won;t speak for other areas, but where I am the Pokemon TCG has exploded in popularity again. I have amassed a large collection (between me and my daughters) and would love to be able to store/sort/analyze here with my MTG and WoW inventories.
Thanks and keep up the great work!
