I too love xenForo and planning to married her... soon!... i just need to divorce my current wife (vb).... i'm not sure what to do with the mistress thought (ipb)! Thank God, i didn't have any kids with either the wife or the mistress... that would have made things more complicated...
Highlight the text you are having trouble with and click the REMOVE FORMATTING button.
The more formatting you have the worse it gets.
One idea that might help would be for posts with tonnes of formatting to ... Post the post when only 1/3 done. Then edit it... add more ... then post ... then edit.. post, etc. (I'm just thinking outloud here )
