The SGMA discussion group is for hobbyists interested in designing, building and displaying modular layouts operating American tinplate toy trains in standard (2-1/8") gauge. Participants should limit their discussion to standard gauge toy-train-module-related topics. Questions or comments about technical aspects of standard gauge modules, standard gauge module manufacturers, and standard gauge modular layouts, are all examples of the type of posts that are appropriate for the list. Please refrain from inappropriate topics and the use of personal invective or "flames." Please do not post in MIME-encoded mail. New subscribers are encouraged to post a brief personal profile to the mailing list so the others on the list may get to know you. Please do not send attachments such as GIFS or JPEGS or other binary files with your e-mail to the mailing list. Only postings from subscribed members to the mailing list will be processed. Therefore, should you or your ISP change your e-mail address be sure to send an update to the mailing list for the new address.
