I'd like to bring your attention to the following blog post, which will explain how you can "Mention others in posts":
You may have seen me do it a bit over the past week, and I also noticed a few others were also using the option to mention others.
e.g. I'd like to demonstrate it by highlighting the fact we have a regular Monday group weigh-in which is run by myself ( Lowcal ) and the Fab 5'ers, who are Prin , suzybenj , Ruth_canal_runner , moreless , and LessToLose. Look for the latest thread in the Events section (right-hand-side of the homepage) if you do would like to see what the Monday group weigh-in sessions are like. I hope you'll join us next Monday for a group weigh-in, if that idea appeals to you.
Please enjoy reading the blog post, and I hope to see you 'mentioning' people around and about in the site, if that option appeals!
Have a great day!
