Advantages and disadvantages of using an external wiki over an internal hosted one

Advantages

• Which you choose depends on how you're using the wiki: If the whole of the course taking place in the wiki it's a VLE in itself. And an external one might give you enough flexibility

Disadvantages

• You may have space limitations
• Possibility of external tech failure (like when educspaces announced it was closing in the middle of people's blogging-based courses - luckily it was saved, but it's a message!)
• Which you choose depends on how you're using the wiki - if is it just a small part of a course using technology it may sit naturally within the institutional VLE and the wiki available within that
