Briefly (as I'm short of time! and the way the guidelines are laid out won't cut and paste easily onto Blogger)
For January/February issues My Weekly are looking for:
1400-1600 words Twist in the Tail. Particularly light hearted or very moving themes.
700 word Coffee Break. Again, light hearted or moving.
1200 or 2000 word Romance stories. Light hearted themes.
2500-3000 Long Reads.
Remember no MSS will be returned now, so if you hear nothing after 6 months consider it rejected. No need for SAEs (though I am sure most people email subs to them these days). Only send one sub a month.
