+Anti-Spam Links for SMF 2.1.x
+================================
+
+This package ports the classic Anti-Spam Links mod from SMF 2.0.x to SMF 2.1.x.
+
+What it does
+------------
+- Blocks external links for low-post members if configured.
+- Rewrites external links as non-clickable text for low-post members if configured.
+- Adds rel="nofollow" to external links for low-post members if configured.
+- Supports guest-specific handling.
+- Applies to post preview, quick edit XML responses, displayed posts, topic summaries, and member signatures.
+
+How this port differs from the old 2.0.x package
+------------------------------------------------
+- Uses SMF 2.1 integration hooks instead of editing SMF core files directly.
+- Adds a Vietnamese language file in addition to English.
+- Keeps settings under:
+  Admin > Posts and Topics > Posts
+
+Settings
+--------
+- Post count under which members cannot post external links
+- Post count under which members external links are shown [nonactive]
+- Post count under which members external links are set [nofollow]
+- Guest behavior:
+  - disable mod for guests
+  - cannot post links
+  - links are shown [nonactive]
+  - links are set [nofollow]
+
+Notes
+-----
+- Internal links to your forum are excluded.
+- If both "nonactive" and "nofollow" thresholds are enabled, the package ensures the nofollow threshold stays above the nonactive threshold.
