Add tags to the specified item:

bool isSuccess = await _client.AddTags(myPocketItem, new string[] { "css", "2013" });

Remove tags from the specified item:

bool isSuccess = await _client.RemoveTags(myPocketItem, new string[] { "css", "2013" });

Remove all tags from the specified item:

bool isSuccess = await _client.RemoveTags(myPocketItem);

Replaces all existing tags with new ones for the specified item:

bool isSuccess = await _client.ReplaceTags(myPocketItem, new string[] { "css", "2013" });

Renames a tag:

bool isSuccess = await _client.RenameTag("oldTagName", "newTagName");

bool isSuccess = await _client.DeleteTag("tagName");
