No idea sorry. Not sure how android saves work or where they are placed. However, there is no Ep8 android, so would suggest using JoiPlay but again, no idea how that works either sorry.
If you click the quote button on multiple different posts, the forum saves them up (for want of a better explanation). When you want to post yourself, click
insert quotes (to the right of attach files) and it will bring up a window showing them all. In this window you can delete, rearrange etc. Click
quote messages and it will put them all into your own post window, then you can reply to them all at the same time so you are not spamming the forum with post after post after post.
