Thanks for the invitation to comment, Russell. I'm enjoying reading about this product re-use. It is an effective learning technique. The Mailman size limit can be changed on a per-list basis, and I've made that change on some mailing lists to compensate for the general increase in connectivity over the past ten years. I'm fine with the limit of 40 KB, though with the practice of top posting there's a higher chance of ordinary discussions hitting that limit without attachments. The file was 35603 bytes in the mail, and 26354 after decoding. The multiplier was 1.35, and was from the base64 encoding, which spreads every 8-bits of input across 6-bits of output. http://en.wikipedia.org/wiki/Base64 A Microsoft Excel spreadsheet is an appropriate way to collaborate in this community, where most of you have compatible software or can figure out how to get it. In the other communities that I'm a part of, the chosen tools would be Google Docs, GitHub, Etherpad, or a Wikimedia instance. Tool choice seems to correspond to age cohort of participants; people tend to keep the tools they first invested in, or currently use. To continue to collaborate with Microsoft Excel spreadsheets once they hit the limit, either; 1. agree with the admins to continue with moderation approval, 2. create a new list for the board and post them there, or; 3. use a file hosting service and post pointers. http://en.wikipedia.org/wiki/File_hosting_service http://en.wikipedia.org/wiki/Comparison_of_file_hosting_services I don't use Microsoft Excel myself because of the license terms and conditions of the product and operating system, but that's a private matter that I feel no need to inflict on you all. ;-) --=20 James Cameron http://quozl.linux.org.au/ --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
