When I try to respond to answers it won't let me. I feel like it's rude not to thank people who helped me on hard problems and I wish I could. Any tips on how to fix this?
Also to everyone thats been helping me with my math, thanks for the help!
Edit: somtimes it lets me put an answer but often it doesn't so I'm thinking it may be a glitch
If you wait too long the thread might be locked.
In which case I think a padlock is displayed, ...at the top I think.
When you make comments like this it is a good idea for you to include a link to the post where it has happened.
Then we might be able to see why it happened.
