有没有办法阻止wordpress中的WYSISYG编辑器修剪掉某些标签？

I'm sick of this WYSISYG editor of wordpress. Every time I switch from HTML view to WYSISYG view & back, it trims out many tags. is one such tag. I know I can force wordpress to disable WYSISYG editor, but is there any way/patch to ask WYSISYG editor not to trim out tags.I'm sick of this WYSISYG editor of wordpress. E
