I'm sorry for the headache I caused you. The birthday problem isn't a huge deal for you and your co-workers to fix right away; it was my fault for not being careful when registering. Still, I'd like to thank you for your time in fixing the problem. The DART community is very appreciative that the team is so diligent about providing feedback and fixes.
Don't worry about it, I am always glad to be of help, it's never a headache :) And thank you for the kind words!
I'm not much of the technical person, so I'm afraid I can't be of much help in image uploading. I do think that it is something that can be very beneficial for the site. Image uploading can make memes on the games forums and suit pictures for fashion. In debating, it might be that a debater would wish to upload a visual aid, such as a map or a graph, both of which can swing debates if used by talented debaters. I, for one, would be visually inclined in voting towards someone who can use data tables and models with skill. Even photography can be extremely powerful; someone in an animal rights debate might (for example) find that the debater could augment his/her argument with photos of abused animals, and someone in a Katana vs Longsword debate might find a visual reference of the physical layout of a Katana incredibly useful when explaining things about physics. Again, I understand that the DART staff is mostly doing this with limited funding and time. I just wanted to throw the idea out there, because I see it as something that would generally be useful for DART, and also as I believe I wouldn't be the only one who would find great potential in it.
There is no doubt that this feature could be highly useful and most likely I will go with the way when a user provides a link to the image and it allows him or her to insert that image into the debate argument but the image will have to be stored somewhere else, which is good enough. The problem with allowing users to upload their own images (instead of linking to them) for the arguments and other things is that I'd have to store them somewhere and that may end up costing me rather a lot because I'd have to pay for ever growing space and bandwidth usage (and that's additionally to other expenses, such as server hosting, domain hosting, CI system, email delivery system, monitoring system and some other). I'll add the donation system at some point later but I don't imagine it's gonna be that effective, but I guess we'll see :)
