Dont worry, there is help for you!

Yes,its true, this forum dont has the Feature "preview" when you are writing posts. Thats a pitty.
BUT dont worry, i will tell you how to live without that feature 😉

There is a nice, easy and even funny way to live with it. Doesnt that sound great? Well it is!
Do it like this:
When you write a Post and want to see a preview because maybe you wrote something italic or
added a surftipp or whatever and you want to see how your post looks like...

You have to be brave now: Just post it!
Yes, dont worry, as long as you write in the first line something like, "Post not complete yet- i am still editing" or "Please wait i am still working on the design of my Post" or "Dont read yet, im am just previewing", than it maybe make me smile (thats the funny part) and you can preview easily (thats the easy part, as you may have noticed), and others know that they should wait with reading if maybe somone get a mail notification and want to read in the mail or is just very fast clicking on your new post, to fast for you while thinking about if it looks good enough for the world. (And telling people that you may still change what you wrote, that is the nice part)

Isnt all that easy, nice and funny to live without that "preview button"?
And maybe, one day, there will be a preview if someone find out how it can be made possible with this forum.
