Ok, since we just got a PM question about this, I figured it would be best to address it here.
ECE dragon game is, to the best of my knowledge, no longer active. If Blitz wants to step in and correct me that's fine, but as of right now, the last I spoke with her she no longer had the time or energy to continue it in its current icarnation. Whether or not this will change in the future, or if it will undergo a revamp into something more simplified, I have NO idea. We have removed the links to ECE from our forums and site. To date, I am still allowing dragons to be gender bent and used to create wyverns, and Blitz told me she did not have any problem with this.
On the subject of those who still own dragons from ECE, you are more than welcome to use those dragons for wyern breeding stock. However, we will NOT be offering dragon for wyrm "trades" to cash in your now unwanted dragons and get wyrm instead. The dragons were purchased from Blitzava. No percentage of the money from those sales was paid to CDF, the same as no percentage of CDF sales was paid to ECE. The two games were separate entities, and sister games only insofar as we both allowed crossbreed in between the two species. As such, players may NOT 'cash in' their unwanted dragons to use as a type of store credit towards wyrms. Sorry, but I have to pay both my staff and myself.
Players can absolutely offer their dragons in the trade section of our forums in an attempt to trade them for wyrms. However, they should be aware that given the price difference between the two, and the inactivity of ECE, this may be a difficult thing to accomplish.
I'm a mite baffled that I would even have to clarify that no, we will not accept dragons as trade/payment for wyrms, but......there ya go. :/
