The EpiData list is planned as a "list without attachments". The problem of attachments is that sometimes they work only if users have certain software. (Apart from EpiData software).
In general all attachments will be stripped (deleted), but sometimes the filters for this are not sufficient.
The advice for users is to:
A. Send mail as TEXT only mail to the list B. Try to generalise the statements in standard text C. Keep volumen low, since with slow internet connections the contents gets to be a problem. There is a limit on size in the list. If we run into problems I might change the limit (up or down).
In other words. Attachments gives different users problems. So please send your questions as ordinary text only. Extended documentation or files can be the user be uploaded to that users own website. And then in the posting to the list refer to that site, where the file is placed.
