I apologize for the error you encountered upon submitting your new topic. There is not a size restriction for posts, but there is a time limit for editing. The error you encountered was due to the post’s creation exceeding this time limit.
To be sure all participants have plenty of time to leave detailed posts, I have extended the time limit to 2 hours. If you think your post will take longer than 2 hours to compose, please consider typing it in a word editor first. Then after completing it copy and past it into the forum.
Thank you for sharing the problem so it could be fixed,
