Allotments 4 All

Why do I have a lock whenever I post a topic, please? In Bargains all 3 topics have a lock on them, what am I doing wrong? Thanks.

They're not locked ani - only you or a mod can lock a thread - I just posted a test response...

Ok thank you, it's just that they have a picture of a lock on the right hand side and I don't know what it means. There again I'm not very good at computer things!
