An excellent Convention Card Editor was written by Lee Edwards of the USA. It could be used to produce convention cards for many countries. Sadly, Lee Edwards decided to stop developing it at the end of 2002, and from then on only develop an editor for ACBL cards. Early in 2004, without any explanation that I know of, the ACBL editor also became unavailable from the ACBL site and Lee's homepage.
Fortunately, Lee's site re-appeared at the end of 2004 and can be found here.
The probable final version of the original editor can be downloaded below. Once you have downloaded the file, unzip it and then run the file inside. Note this version does not include the ACBL card so you will have to download the ACBL card CCE separately.
The most up-to-date version I have of the ACBL editor is also available below. It is version 1.0.10. Once you have downloaded the file, unzip it and then run the two files inside, the large one first, and then the other [an update] next.
Note these files are enormous. Even zipped, they contain over 3MB each. Especially if you have a slow connection you may find the download times are long.
If you do not have a facility to unzip documents then you should download an evaluation copy of WinZip which is available at the WinZip site
