You are not using strikethrough inside words today, are you?
I am sorry, but I don't understand you. What do you mean by "today"? I am with Wikidot from 2008, and all tis time em-dash is made using two hyphens. As if anything changed. And if there were any changes, I am not aware of it. I still use two hyphens for em-dash effect. Again, what do you mean by "today"?
How do you make your em-dashes work today?
Maybe I do not read you correctly, but you don't read me at all, I am afraid. I already explained how I get the effect of em-dash. I will quote myself:
but in Wikidot, if it is repeated in the same row, it makes strikethrough, so I have to go somewhere to copy the real em-dash (—), to paste it, and in this way to get two em-dashes in the same row and not stricken through text. I did it only when it was necessary, meaning when there were two em-dashes in one row (or paragraph, I am not sure).
Where "if it is repeated in the same row" means this:
--blah blah blah--
which gives:
blah blah blah
Which is completely the same as example of the em-dash between the years I gave earlier.
And "I did it only when it was necessary" means that if there are no two em-dashes in the row, I don't go around copying the real dash and pasting it, but use two hyphens.
If you want to know what I mean by "real em-dash" edit my post and see this: —
I am really sorry for my more than poor English. I am not a native, you know… :P
