Hello @randdmart

You can upload your file to a cloud storage and share the link to it.

Other than that, please refer to my comment about trust levels here:

Community rules

Dear @lop25 When a user enters the forum, they are granted with very first level of trust that does not allow attaching the files to their posts and relies. This possibility becomes available once user reaches next level of trust. The conditions for that are as follows: Entering at least 5 topics Reading at least 30 posts Spend a total of 10 minutes reading posts I hope it helps.
