I am downloading rare TV series (each file has less than 5 sources). Actually I have to download only 3 episodes from eD2k/KAD, because I have remaining episodes from my friend via Sneakernet. I put these files in my "Shared folders", so other eD2k/KAD users can download them from me. And few people are downloading these files from me. I thought that these people will have lacking episodes and maybe I will ask for sharing them (to make more sources) or for giving me a slot. So I decided to write message to user, but I got message that chat is protected by CAPTCHA and I my client (aMule 2.2.6) isn't supporting it. So I upgraded to 2.3.1 RC1 (manually compiled it from source). Now after sending message, window appears with CAPTCHA image. When I solve it, I switch to "Messages" tab in aMule window and I see text in chat field
*** You have passed the captcha check and the user has received your message. ***
*** Failed to Connect to client / Connection lost ***
and my uploading to that user stops.
I tested it only with users using aMule 0.50 because I don't want to accost someone just because (s)he uses eMule 0.49.
