I think the first thing you’ll have to do is to save the Word file as text. Then you’ll need to check the import scripts to see which one will fit the Thingamablog format. Or perhaps do a search for such a script.
If your posts are plain text (i.e no links or other html content), then you can use MS Word Save-As-Text and use one of WP’s bulk import functions.
If you need to preserve the formatting, then it might be a bit of a longer process. In this case, you should use MS Word’s Save-As-Filtered-Html file option and save your Word content as a html file.
Once you have the html file, you can:
1) Open the html file in IE or Firefox and copy/paste the relevant content to WP Admin rich text editor or paste to an offline editor such as Zoundry Blog Writer (that us).
2) Open the html file directly from an offline editor and post to WP.
3) Or, copy & paste directly from MS Word to an offline editor. I know Zoundry should attempt to clean up some of the MS Word/Office html markup.
The only downside is, the offline (desktop) client apps do not have a “bulk” upload functionality. So, you might have to do on a per post basis.
